Quinn Emanuel is generally recognized as one of the premier firms in the United States for high-stakes business litigation. With more than 650 lawyers and 11 offices worldwide, it is the largest law firm in the world whose practice is devoted exclusively to business litigation.

The firm's largest practice area by far is intellectual property litigation. Its regular IP clients include technology leaders such as Cisco, Google, IBM, Johnson & Johnson, Motorola, Roche, Samsung, SONY, Symantec and many others. The American Lawyer, the leading US legal periodical, recently gave the firm the prestigious Intellectual Property Firm of the Year award.

Quinn Emanuel offers the same high quality IP representation in Germany, which is the epicenter of EU patent litigation. In Hamburg and in Mannheim (the location of one of the most important patent infringement courts in Europe), the firm specializes in both intellectual property and related antitrust litigation.
